Raff most recently served as senior editorial producer at Piers Morgan's CNN talker and previously was a producer at The View and a talent executive at The Martha Stewart Show and Late Night With Conan O'Brien.

Meyers will transition to the Lorne Michaels-produced Late Night after Fallon replaces Jay Leno as the host of The Tonight Show.

The late-night booking hierarchy is in for something of a shift with The Tonight Show's move from Los Angeles to New York.

That would seemingly make the landscape all the more competitive as all three shows (produced by Michaels) will be competing for guests with CBS' Late Show With David Letterman and Comedy Central's The Daily Show With Jon Stewart and The Colbert Report.
